She makes you want to Shout: From 15 to 65, Lulu's age-defying face - The singer looks as youthful as she did in 1964

She was a fresh-faced 15-year-old when she shot to fame with her first and biggest hit, Shout, in 1964.

And at the Commonwealth Games closing ceremony on Sunday, singing the same song a full half-century on, Lulu was looking as youthful as ever — her megawatt smile still plain to see.

The singer looked fantastically trim in a pair of bold tartan trousers and the fedora hat which she has taken to wearing of late. But those watching could only speculate as to how she looks so good aged 65.

We looked back over the many faces of Lulu and work out how life, love — and Botox — have contributed to her youthful glow.

1964 (left): This is the year Lulu hit the big time with Lulu & The Luvvers. Aged 15, she’d been singing in clubs in Glasgow since she was 12; 1968 (right): A more sophisticated look, but Lulu is still only 19. Lulu met first husband Bee Gee Maurice Gibb around this time, backstage at Top Of The Pops. They married in 1969

1970: (left) On her TV show It’s Lulu, the pillow-cheeks are starting to slim as she matures. She wears heavy make-up, perhaps to cover the acne she hated; 1972: (right) Pale, with a dramatic haircut, her marriage to Gibb was breaking down and they split in 1973. She later blamed his heavy drinking in part for the divorce

1973: (left) Looking winsome on the show It’s Tarbuck, with her hair in a sophisticated top-knot and glamorous make-up to accentuate those cheekbones; 1977: (right) Hard to believe this regrettable perm, as by now Lulu was with her second husband, hairdresser John Frieda. They had a son, Jordan, in 1979

1985: (left) Playfully acknowledging her Scots roots as Isla St Porridge in BBC’s Super Gran. Her hair is long and the petite star's in great shape for 37; 1986: (right) Looking mumsy, with a Sharon Osbourne crop and Pat Butcher earrings, it’s Lulu in her Freeman’s Catalogue era. And a hint of a double chin for the first time

1993: (left) She revived her career thanks to her vocal on Take That’s Relight My Fire. Note the very firm jawline and the apparently stretched skin over the cheeks; 1999: (right) Suddenly a blonde bombshell, Lulu has had a style overhaul to host the National Lottery’s Red Alert show during one of her many comebacks

2003: (left) Now 45, there is no movement about Lulu’s mouth and cheeks, despite her animated expression. She admitted later: ‘I used to use Botox, but not any more'; 2004: (right) Is this really Lulu? Pictured from an unflattering angle at a London party, she looks positively pudgy around the face, and rather slack-jawed

2006: (left) A BBC portrait taken when Lulu was a judge on celebrity singing show Just The Two Of Us, and she looks more like Hillary Clinton than Lulu; 2009: (right) With a flattering fringe, Lulu is 60 yet looks 20 years younger. She has launched her anti-ageing products range and her face is the perfect advertisement

2011: (left) Lulu is getting ready to chat to Loose Women — daring to show off her crows’ feet, but still with remarkably plump cheeks; 2013: (right) The hamster cheeks are back as she appears on ITV’s Lorraine Live, with a full face and peculiar hat. Is it hiding something that’s gone wrong on her forehead?

2014: A force of nature at the Commonwealth Games closing ceremony, 65 and not a crow’s foot in sight. Can it really be, as Lulu says, due to Time Bomb, her own brand of face cream? She reprised her hit from fifty years ago and two husbands later, she looks as good as ever. She really does make you want to shout!
